Concept explainers

Refraction is a change in the direction of light rays when they travel from one medium to another. It is the bending of light when it goes through different media.

Angle of Refraction

Light is considered by many scientists to have dual nature, both particle nature and wave nature. First, Particle nature is one in which we consider a stream of packets of energy called photons. Second, Wave nature is considering light as electromagnetic…

Index of Refraction of Diamond

Diamond, the world’s hardest naturally occurring material and mineral known, is a solid form of the element carbon. The atoms are arranged in a crystal structure called diamond cubic. They exist in a huge variety of colours. Also, they are one of the bes…

An object is located in air 32 cm from the vertex of a concave surface made of glass with a radius of curvature 15 cm. Where does the image by refraction form? Use nair = 1 and nglass = 1.6. (Give the image distance in centimeters.) What is its magnification?

An object 1.30 cm high is held 3.00 cm from a person's cornea, and its reflected image is measured to be 0.167 cm high. What is the distance from the cornea to the image? Determine the magnitude of the cornea's radius of curvature.

The magnification of the image formed by a refracting surfaceis given by M = - n1q/n2pwhere n1, n2, p, and q are defined as they are for as shown and as shown. A paperweight is made of a solid glass hemisphere with index of refraction 1.50. The radius of the circular cross section is 4.00 cm. The hemisphere is placed on its flat surface, with the center directly over a 2.50-mm-long line drawn on a sheet of paper. What is the length of this line as seen by someone looking vertically down on the hemisphere?
